Before diving into the upgrade process, ensure you meet the following prerequisites:
Data Backup: Make a full backup of your device using Samsung Kies, Google Takeout, or another preferred method. This ensures that you do not lose any crucial data during the process. Activate Another Device: Do not use your Galaxy Note 4 as your main device during the process. Activate another device to ensure you can use it if something goes wrong. Proprietary ROM: If you decide to use a custom ROM, ensure you have the compatible file and installation instructions. Fast Internet: A stable and fast internet connection is necessary for downloading the necessary files.Step 1: Unlock the bootloader
Unlocking the bootloader is a crucial step as it allows you to flash a custom recovery or custom ROM on your device. Here’s how to do it:
Ensure OxygenOS is installed on your Galaxy Note 4 (the stock firmware). Download and install Samsung USB Drivers on your computer. Connect your Galaxy Note 4 to your PC via USB. Download and install the Samsung USB Installation Tool. Unlock your bootloader (through Samsung Kies or Samsung USB Installation Tool) following the on-screen instructions. Note that doing so will erase all data on your device.Step 2: Install TWRP (Team Win Recovery Project)
TWRP is a custom recovery that allows for easy flashing of custom ROMs. Follow these steps to install it:
Download and install TWRP for the Galaxy Note 4 from the official website or a trusted source. Extract the downloaded file to your computer. Connect your Galaxy Note 4 to the computer via USB and enable USB debugging in Developer Options. Install TWRP by following the prompts through the USB Installation Tool.Step 3: Root your Galaxy Note 4
Rooting is a necessary step for flashing custom ROMs and TWRP:
Download the appropriate rooting package from a trusted source: Ensure it is compatible with your Galaxy Note 4 model and firmware version. Connect your device to your PC and enable USB debugging in Developer Options. Extract and start the rooting process using the rooting tool. Follow all on-screen instructions. Once rooted, re-flash the TWRP recovery using the same steps as above.Step 4: Flashing the Custom ROM
Now that TWRP and root are in place, you can proceed with flashing a custom ROM:
Download the desired ROM from a reputable source (e.g., CWM, CyanogenMod, Stock ROMs, etc.). Backup your current system through TWRP if you are concerned about losing any critical data. Insert the ROM file into a folder on your computer, and then mount the SD card on your Galaxy Note 4. Boot into TWRP recovery mode and select 'Install'. Find the ROM file and begin the installation process. This may take some time, so be patient. After the installation completes, reboot your device and verify the upgrade.Conclusion
Upgrading your Samsung Galaxy Note 4 to Android 7.0 can significantly enhance your device's performance and features. By unlocking the bootloader, installing TWRP, rooting your device, and finally flashing a custom ROM, you can enjoy the latest Android features without the need for regular updates from Samsung.
